FLUID-DISPENSING 1?.PPARATUS.

Application filed December 16, 1921.

T0 all w/iom it may concern.

Be it known that 1, JOHN J. CATRON, a citizen oi the United States,residing at Bonham, in the county of Fannin and State of Texas, haveinvented certain new and useful improvements in l luid-DispensingApparatus. of which the following is a specification.

This invention relates to new and useful improvements in "fluiddispensing apparatuses.

The object of the invention is to provide means tor automaticallyoperating a drain valve for draining the measuring receptacle ot avisible dispenser, when the door oi said dispenser is fastened in itsclosed position; as well as for releasing said valve when the door isuntastened.

A. further object is to provide a dispenser of the character describedin which the parts are compactly. economically and conveniently arrangedand their number reduced in a practical manner.

In carrying out the invention a drain pipe is extended from themeasuring receptacle and connected with the overflow or other pipe whichreturns fluid to the underground tank. A self closing valve is connectedin the drain pipe and located so that its stem is engaged by thefastening element or the dispenser door, the said valve being normallyclosed. Vhen the door is closed and its fastening element swung into itslocking position the valve stem is depressed and the valve opened,whereby the receptacle is au tomatically drained.

A construction designed to carry out the invention will be herein'atterdescribed together with other features of the invention.

The invention will be more readily understood from a reading of thefollowing speciiication and by reference to the accompany ing drawingsin which an example of the invention is shown and wherein:

Fig. 1 is an elevation of a dispenser CO11- structed in accordance withmy invention,

Fig. 2 is an enlarged vertical sectional view of a portion of thedispenser,

Fig. is a similar view at right angles to Fig. 2,

Fig. 4 is a cross sectional view taken on the line 4l4-. of Fig. 1,

Fig. 5 is a cross sectional view taken on the line 5-5 of Fig. 1,

Fig. 6 is a cross sectional view taken on the line 6-6 of Fig. 3, and

Serial no. 522,897.

Fig. 7 is a sectional detail of the drain valve.

in the drawings the numeral 10 designates a cylindrical cabinet having abase :tiange ll. a doorway 12 and a door 13 mounted to slide verticallyin the doorway. A. hasp 1%- is hinged to the upper outer side of thedoor and is adapted to engage an eye 15 mounted on the cabinetimmediately over the doorway.

A base plate 16 is mounted on top of the cabinet and has an annularflange overhang ing the same. A transparent cylinder 1? preferably ofglass is mounted on the plate within the flange and may be surrounded byan open mesh guard 18. A cap or dome 19- is mounted on top of thecylinder and is tastened by vertical rods 20 having their lower endssecured in the base plate, whereby the cylinder is held in place.Suitable fluidtight joints (not shown) are provided at each end of thecylinder, which with the base and cap form a visible measuringreceptacle. An electric lamp globe 21 may be mounted on top oi": thecap.

The base plate 16 is preferably cast with a depending boss 22 having apassage 28 ex.- tending from the centerto rear side of said plate. Anoverflow tube or column 24: is mounted centrally of the cylinder 17 andhas its lower end screwed into the plate in registration with thepassage his tube is fixed against movement and has its upper endterminating below the upper end of the cylinder, whereby fluid deliveredto the cylinder will overflow into the tube at a predetermined level,thus assuring an accurate measure which cannot vary. '1 1e cylinder maybe subdivided within the length of the tube by placing on said cylindergraduation marks at the proper elevations to measure the difierent unitsinto which the measure is divided. 4

A return or ove'rilmv pipe 25 has its upper end screw threaded into therear of the boss 22 so as to connect with the passage 2 This pipe issuitably connected with the urderground or storage tank which containsthe fluid which is dispensed by the device. A supply pipe 26 extendsupwardly within the cabinet at one side thereof and the liquid may beelevated in said pipe in any suitable manner by means which is notconsidered necessary to illustrate. This pipe is connected with a T 27.A pipe 28 extends Cal from the T 27 and is extended upwardly at rightangles so as to enter the bottom of the plate 16. The gasoline or otherliquid supplied thru the pipe 26 passes thru the T 27 and by way of thepipe 28 into the measuring receptacle. When the measuring receptacle isclosed the gasoline will overflow at the top of the tube 2 1 so that anaccurate measure will be had.

A drain pipe 29 extends downwardly from the plate 16 and is turned atright angles so as to connect with a drain valve 30, which isillustrated in detail in Fig. 7. The valve comprises a spring pressedvalve 31 normally closing on a seat 32. A plunger pin 33 is mounted inthe valve so as to engage the stem thereof and to project forwardly fromthe valve casing. hen the pin is pressed inwardly the valve is unseatedand opened. Normally the valve is closed so as to prevent the passage ofliquid therethru. A pipe 34: leads from the valve and extends rearwardlyas is best shown in Fig. 6. This pipe is bent at right angles andconnected with the overflow pipe 25. It will be seen that when the valve30 is opened the liquid from the measuring receptacle will pass downthru the pipe 29, thru said valve and by way of the pipe 3 1 into theoverflow pipe 25, whereby the receptacle will be drained. Before thereceptacle can be filled the valve 30 must be closed.

The mechanism for elevating the liquid thru the pipe 26 is, of course,mounted in the cabinet 10 and is accessible thru the doorway 12. Whenthe door 13 is closed said mechanism is not accessible and liquid cannot be elevated in the pipe 26. In order to automatically drain thereceptacle when the door 18 is fastened I provide a stud 85 on the rearof the hasp 14- and locate the same so that it will pass thru anaperture 36 in the cabinet immediately above the doorway. The plungerpin 33 is located so as to register with the aperture and to projectinto the path of the stud 35. Thus when the hasp is swung upwardly toengage the eye 15, the stud will penetrate the aperture and engage thepin 33 so as to force the same inwardly, whereby the valve 81 will bedisplaced from its seat 32 and the valve opened. By this arrangement anygasoline or liquid remaining in the cylinder 17 will be drained thru thepipes 29 and 34, and conducted into the overflow pipe 25. This is asafety feature makes it impossible to fasten the door withoutautomatically draining the visible measuring receptacle.

When the hasp is swung away from the eye 15, the pin 33 will be releasedso that the valve 31 may automatically close and thus when the cylinder17 is filled the gasoline will fill the pipe 29, but cannot pass thevalve 30 which will be closed. It is, of course, impossible to obtainaccess to the controlling means for elevating the gasoline until thedoor 12 is opened. The T 27 has connection with a dispensing valve 37which may be' of any suitable type, and is provided with an actuatinglever 38. A hose 39 is connected with the valve by means of a coupling40, and this hose is equipped with the usual nozzle, not shown. When thehose is not in use it may be inserted within the cabinet and thusenclosed when the door is shut.

I connect a vent tube 41 to the coupling below the dispensing valve 37and extend this tube upwardly so that it enters the cap 19 above theover-flow level of the liquid. The purpose of this vent tube is toprevent an airlock in the hose 39 and to provide a free passage of airso that the dis pensing operation may be efficiently carried out. Thisvent device is fully described in my Letters Patent No. 1,391,245,issued September 20, 1921.

Various changes in the dimensions and shape of the various parts as wellas modifications may be made without departing from the scope of theappended claim. It is obvious that a device of this character permits ofalterations and the substitutions of different parts as for instance thedispensing valve 37, the type of drain valve 30 and the specificconnection of the supply and drain pipes.

What I claim, is:

In a fluid dispenser, the combination of a cabinet, a liquid measuringreceptacle carried by the cabinet, means for supplying a liquid to thereceptacle, means for dispensing liquid from the receptacle, a drainpipe extending from the receptacle, an overflow pipe connected with thereceptacle and having connection with the drain pipe below thereceptacle, a normally closed drain valve interposed in the drain pipeand having a pro jecting operating element, a vertically sliding doormounted in the cabinet, the drain valve being located above the doorwayof the door, and a hasp mounted 011 the upper end of the door andengaging the valve cu erating element to open the valve when the door iselevated and fastened.

In testimony whereof I afliix my signature.-

JOHN J. CATRON.
